Background

Automatic Meter Reading (AMR) technology enables the automated collection of consumption, diagnostic, and status data from utility meters—such as those for water, gas, and electricity. By utilizing cellular 4G/3G communication, AMR systems transmit real-time data to central databases for billing, troubleshooting, and analysis. This automation eliminates the need for manual meter readings, reducing operational costs and enhancing data accuracy.
